	If you *do* have OpenWindows, you also have something
	called "xps" (under $OPENWINHOME/demo/xview) that is
	another XView app that talks to the NeWS side of
	the server.  You write NeWS code in the TEXTSW,
	hit run, and rendering happens in the canvas below.
	Or you drag-n-drop PS files from the OPENLOOK filemanager
	into it (a la Pageview).

	You also have "psh" which opens a TTY connection to the
	NeWS side of the server.  For an interactive session,
	you type in "executive" and you're off (or you can write a psh script).
	Default rendering happens in the framebuffer, or you can 
	create a little NeWS canvas (a trivial one-liner) for your rendering.

	With a tiny bit more work (and I do mean tiny), you could also
	use the O-O TNT toolkit to create an app that renders PS and
	has an OPENLOOK interface.

	Pageview does have its faults (OPENLOOK *users* are confused when they
	drag the image around... how about OL-style scrollbars?) but usually 
	I've found the PS files to be offending by not conforming to EPS spec.

	Re: reverse mirror images.  This one took a while to discover. 
	Try commenting out the "initgraphics" someone in the top of your
	PS file, then try running pageview again.

	ie (this one works for me),

		sed 's/^initgraphics/%initgraphics/' < psfile | pageview -
